The unveiling of the newest Apple iPhone was greeted with typical fervor last week. The slimmest ever, it can be taken anywhere—including to the bathroom, where, statistically, you probably will use it.

Among those in competition at the Westminster Dog Show this week is Elias, a Beauceron who spends his time off the runway sniffing out gluten in food to protect people with celiac disease. And as scientists better understand the power of a dog’s nose—100,000 times more sensitive than a human’s—canines are moving into other professions, too.

Isaiah Mustafa, a.k.a. the Old Spice Guy, rode—both a horse and a motorcycle—to fame earlier this year with a series of commercials featuring his tongue-in-cheek portrayal of a masculine ideal that managed to make a stale brand suddenly fresh. He came clean to NEWSWEEK about the secret to his success.

“It’s organic!” is usually a selling point at the upscale Astor Wines and Spirits in Manhattan. When Colin Spoelman says it, hawking a table of small bottles featuring vintage-chic labels from his Kings County Distillery, he gets mostly laughs. Maybe that’s because he’s selling organic moonshine.

In 1972, when Mae Jemison was just 16 years old, she arrived at Stanford University, where she intended to pursue a degree in engineering. But it wasn’t long after arriving in Palo Alto that she learned that the university’s science departments weren’t nearly as enthusiastic about her as she was about them.

This week’s New York magazine includes a piece called What If Women Ran Wall Street by Sheelah Kolhatkar, analyzing testosterone’s effects on the male-dominated world of trading. It’s not an altogether new point. Our own Mary Carmichael talked about it a couple of years ago. And economists at Davos last year argued that the presence of more women on Wall Street might have averted the banking crisis. "Women are more cautious," Muhammad Yunus, the head of Grameen Bank, said at the time. "They wouldn't have taken the enormous types of risks that brought the system down."Kolhatkar’s piece is fresh in that it studies the impact of hormones like testosterone in a more thorough way than ever before, which, as XX Factor’s Hanna Rosin points out, "sure is satisfying":For one thing, the old idea of men and markets on the side of the rational and women on the side of emotionalism takes a blow. For another, testosterone seems to be the new cultural hormone,...

For a journalist there’s hardly anything more satisfying than seeing one of your stories have an impact. So imagine my delight when I received a joint letter from David Kennedy and Gary Slutkin, the two men whose work—and rivalry—I examined in “The Battle of the Antiviolence Gurus." It seems the two have put aside their differences in pursuit of a common cause: taking issue with the way I portrayed their work. I stand by my reporting on the story, but I welcome their comments. And, fortunately, another truism about this particular field is that if you piss off both sides equally, you’re probably doing your job. After the jump, see their joint response to my piece: Dear editors, Jesse Ellison’s Jan. 6 article [“The Battle of the Antiviolence Gurus”] underemphasizes the most important aspect of our work—that we have both found ways to reduce community violence. And it fails to recognize our joint commitment to solving the problem of urban violence, as well as our respect for one...

The current cost to station 68,000 U.S. troops in Afghanistan: just over $65 billion—or, to quote a figure politicians have extrapolated, about $1 million a soldier. (Obama's budget director has cited this ratio in estimating surge costs.) Why so much? A breakdown, using 2010 Defense numbers:
